Abstract
A drum acoustic wire assembly installed on a drumhead, including a plurality of acoustic wires disposed side by side in a direction perpendicular to the direction of the axis of each one of the wires, and a pair of wire holding plates that hold both ends of the acoustic wires. The acoustic wires are coil-form wires and are connected by soldering to the undersurfaces of the tip (inner) end portions of the wire holding plates. Projecting portions are formed on the undersurfaces of the base ends of the wire holding plates, so that, when the acoustic wires are in contact with the drumhead, the tip (inner) ends and the base (outer) ends of the wire holding plates are at substantially the same height or the tip ends are lower than the base ends.
